Abstract

Cyano-mediated interaction of the alternating high-spin Mn(II) centers and low-spin Ru(III) centers in {Mn[Ru(acac)2 (CN)2 ]2 }n (Hacac=acetylacetone) results in long-range ferromagnetic ordering below 3.6 K. This novel Mn(II) Ru(III) coordination polymer, which has a diamond-like structure, was constructed from [Ru(acac)2 (CN)2 ](-) and Mn(2+) ions.

Keywords: coordination polymers; cyanides; magnetic properties; manganese; ruthenium.
